Marantz has long been a source of premium high-fidelity audio components built primarily for connoisseurs. Now, even music lovers on a budget can enjoy that legendary Marantz sound thanks to the SR4023 stereo receiver. It makes an ideal centerpiece for those who want a top notch, two-channel audio system that won't break the bank.

Renowned Marantz design and performance
Meticulous engineering and high-quality construction are the hallmarks of Marantz receivers. The SR4023 starts with a front panel made of fiberglass-reinforced aluminum. This advanced composite material helps shield internal circuitry from performance-robbing interference and vibration. Inside, this receiver's oversized power supply and fully-discrete amplifier design pack plenty of high-current power to deliver the excitement and dynamics of your favorite tunes.

Flexible connections
The receiver's back panel offers enough inputs to hook up a total of eight components, including a turntable, and four audio/video components. A set of pre-amp out/main-amp input jacks let you add an external power amp for future system expansion. And Marantz even included an output for connecting a powered subwoofer. Plus, the SR4023's RS232 port and infrared flasher inputs allow you to operate this receiver as part of a whole-house system.

The sound solution for the less-is-more movement

On one hand, you want something that sounds much better than an iPod® or Bluetooth® speaker. On the other hand, you want something less complex than a surround sound system. You'll find your sweet spot in a stereo receiver. In addition to being easy to set up and use, many now offer Internet radio and other network music options. Add your music source and two speakers, and you're ready to relax and enjoy your tunes. You might even connect your TV for improved sound with movies and shows.

Not so great.

The sound is shallow and lifeless. Bass lacks punch. Treble is way too high and shrill. I had it hooked up to pair of Eosone RF1000,with built in power bass, and a pair of 22 year old pioneers, with 16" woofers. The bass and treble controls make little difference in the sound, and they can only be adjusted by 2 DB at a time, instead of 1. I contacted Crutchfield and talked to an adviser. Told him of the problems, hoping he could talk me through some way to adjust it. I've talked with Crutchfield in the past and have always been satisfied with them. However, when I told him of the problem, all he said was, 'sounds like an odd defect to me. I've sent out a new one'. I didn't want a new one of this model, and did not ask for one. But being that it was already on the way, I thought I would give it another shot. It arrived very quickly(Crutchfield is great for fast delivery). Anyhow, on with the review. I hooked it up, and got the same results. I thought it may need a break in period. I've had this now for about 6 months. No improvements in sound quality what-so-ever. I feel I gave it very good chance to redeem itself, and it failed. I had enough. Over this last weekend, I removed it from my system, and hooked my entry level cheap Sony receiver back up. It even sounded much better than this one. I got more, and better bass, and better sound quality all around. I'm not saying the sound on the Sony is good. I am saying it is better than the sound on this unit.

Pros:Build quality seems very good. Looks great, with that nice black finish and softened edges.
It is no longer available for purchase.

Great Receiver

This receiver does everything that I need it to do. It has enough inputs to handle my tape decks, CD player, and even my home XM Receiver. Even the FM portion of the 4013 sounds great, pulling in a clear FM Stereo signal from a transmitter that's 50 miles away.

Pros:Looks, runs cool even when pushed hard, great sounds.

Cons:Tight working area in back when connecting accessories, especially for fat-fingers.

trouble

oh boy where do i start. bought this sr4023 about 2 yrs ago and about 1yr into ownership the receiver would not turn on and the panel said "protect mode". once in awhile it would turn on so i just left it on and just muted it. finally got the time to drive to portland oregon (60 miles) to the warranty repair store and after a month there they said they had most parts to repair it except 1, a circuit board, which is backordered, Indefinitely!!!!!!!! eta unknown!!!!! they said that marantz may elect to give me a refurbished receiver and im not sold on that, as i paid big bucks for this one and don't want someone else's headache. needless to say i'm very unhappy with marantz and their products. i always bought cheap boom box units and they lasted much longer than this one. i always wanted a high end stereo set and i thought this one was it, but i guess not!!!!!!

Pros:worked good when it worked.

Cons:replacement parts support is not up to my expectations. parts needed for repair are back ordered. and eta unknown. unacceptable!!!!!!!

No frills, good quality

The Marantz name impressed me, though my audio electronics repairman friend said my old Pioneer would outlast it. If it lasts as long as my old Pioneer, it will outlast me. Performance is excellent, except for FM reception which is a little weak with the included antenna. The controls are a bit arcane, and the reliance on the remote control, belies the otherwise simple design. the source selection via a knob is counter-intuitive and the stops are too shallow to feel easily. I like the clean all black look, no hokey brushed plastium panels.

Nice to have a music around the house again.

Written By JimMcD, Winston-Salem, NC on Monday, February 11, 2013

I purchased the Marantz SR4023 after I took to time to build some great stereo speakers (like the ones I remember but they don't build anymore) and wanted a quality reciever with ample power. I remembered my brothers' 60 watt Marantz back in the late '70s and felt comfortable ordering this model. I was very impressed with the quick 2 day delivery and couldn't unpack it fast enough. After I hooked everything up and powered the system on I was rewarded with that nice Marantz amp warmth. I am lucky enough to work from home so I get to run the receiver all day long. Even running hard for several CDs I find that it runs pretty cool in the cabinet I house it in. Like another reviewer I initally had a problem getting any real "THUMP" out of my speakers while playing CDs. I was using my BlueRay player hooked thru the DVD input and when I was hooking up a turn table I decided to move the BlueRay to the CD input and WOW! That's what they don't tell you. If the input is designated for A/V it is equalized differently from the other audio inputs (I suspect to help thorw the voice frequencies out front). I orederd a multi CD player from Crutchfield to dedicate to CDs. The radio receives very well as we are in a lower area, even with the string antena. The volume control took some getting used to but overall I love this receiver.

Pros:It's a Marantz, nice "heft" to it, good radio reception, Fills my house with music again.

Cons:Cannot control the Bass or Treble from the main unit, only from the remote.

Clean Sound

Purchased to replace/upgrade my Harmon Kardon 3480 Receiver. Man, what a difference! Very clean sound emerged immediately with no distortion. Now, part of the credit probably has to go to the speakers, too. I also just replaced Bose 901's with PSB Image 6's. Not that the 901's are a bad speaker, I just don't have the right room dimensions. The PSB's did not sound good with the 3480 - very muddy at moderate to high volume. I have not tried the 901's with the Marantz, but am betting they would sound better, too, just limited by the unusual room acoustics. So, the 4023 with good speakers sounds amazing. I heard things I never heard before while playing Led Zep's Zoso album on my Technics 1210. Pushed the system to -10 dB, no distortion, very clean mid-range, crisp highs, and with a subwoofer engaged, the lows rocked. The real star was the mid-range, which in the past I have hated so much I had to use an Equalizer to downplay those frequencies. I am happy to say I no longer have a need for an equalizer. The Marantz gives up 40 watts/channel to the HK, but as I've been told for years, there is a big difference in "watts" and "true watts." This Marantz, although it is not a Reference Series amp, is a serious improvement in sound quality.

Pros:Clean Sound across all frequencies - No distortion
Automatic source switching - CDR/Mini-Disc/Open Reel can all record off source without tape monitor button engaged

Cons:Runs hot when pushed - needs good ventilation
Wish it would come in a 70's Stainless look (!)

The Marantz SR4023 is a Power House

I just received this receiver from Crutchfield, a very good, trusted company with a professional staff and good technical support. My old 1973 Pioneer 727's balance pot. went on the blitz and it was time for an upgrade. This Marantz has the same features as the old Pioneer and a little more. Granted, it doesn't have the solid wood case or the stainless steel faceplate as the vintage components but it is NOT plastic and outside/inside the product is very well made. Like the old Pioneer, it doesn't skimp on features audiophiles want. 80 watts of RMS power - 8 ohm speakers is more than enough to power my Bose Acoustimas system in one room. Plenty of analogs for the CD, DVD, Aux and two tape decks and a phonograph mm pre-amp output to hear the warm sound of vinyl. While the Direct Source button gives you "pure" sound, I have my old (1973) Soundcraftsman equalizer fine tuning the sound output. The digital display is large and easy to read and easy to program the tuner radio bands. The unit is lighter and slightly smaller than the old vintage which makes it easier to move it around for cable hookups. I do wish Marantz would have included a balance pot. While this may not be a big concern if your seated dead center in the stereo field, it could have an effect on the listening. I have a Tandberg TD 20A reel-to-reel tape machine where I can adjust the balance through the tape VU meters. All in all, it's a nice unit for the price. I'm very happy with this unit!

Pros:Nice metal cabinet, easy to use remote control, large/clear front display, plenty of in.out jacks for all external components, pre-amp for the phonograph,
Clean sound for a one room zone with plenty of RMS power, the am radio antenna supplied works well but you may need an outside fm antenna for better reception.

Thee BEST Receiver I ever Owned!

This Summer I bought my first CD player since the 1980s! I bought a Mid-Priced Marantz, And I LOVE it! So, I got rid of my Panasonic Receiver that I had for about 20 years! And bought this AWESOME Marantz Receiver! I LOVE it! Thee Best Receiver I have ever owned!

Marantz SR4023

The Marantz SR4023 is nice but I am disapointed that it does not make the bass thump like I thought it would. I am using an old pair of Bose 301 and Bose Acoustimass speakers. I use to have a Marantz that use to make these speakers rock. Maybe I need an equalizer.

Ahhh, Vinyl

It's so nice to hear the crackle of vinyl again. My new Marantz turntable is fantastic, easy to use, sleek, understated and elegant.

Cons:The directions don't indicate that you need to wrap the rubber band (black) around the wheel and spindle underneath the platter - no where in the directions is this step mentioned. However, it's crucial.

Excellent receiver

Excellent sound. Have hooked to a Marantz CD6004 and the sound is incredible. Warm sound as always Marantz have done it. Has a sub preout a main in pre out coupler so you can connect an equalizer if you like. At the beginning there was no sound on the main speakers but Chris from Crutchfield assisted me and the receiver worked perfectly thanks Chris for your patience. As always Crutchfield with the best service on the internet by far.

Great !

Had an Onkyo Reciever for years, it stopped working right. Bought this and the sound quality is great. Very nice. My old Onkyo CD player still works but will be upgrading to an Marantz CD player soon for even better sound. Onkyo is not what is use to be.

Excellent sound and reception

This receiver replaces an old Tandberg receiver and is connected to a Marantz CD player, Thorens turntable, Tandberg dassette deck and ADS speakers. The installation was a snap with the various types of connections clearly marked on the rear panel of the receiver. The receiver works well with all the components and the tuner works very well with the included antennas. The front panel of the receiver matches the Marantz CD player and looks great in the teak cabinet. The remote control is easy to use and uses a slightly different color pattern to easily distinguish it from the CD player remote. All in all it is a great product for a reasonable price.

Pleasantly Surprised

Written By wayne, Greensboro, NC on Saturday, December 19, 2009

This receiver replaced an Onkyo receiver that I had for many years (I consider myself an audiophile but at the time, Onkyo receivers was pretty high end). Also, I've always believed that when purchasing your first high end stereo, you should determine how much you want to spend on your system and invest 50%of the cost in speakers- that's because speakers can make the biggest difference in the sound.

Well, maybe speakers can make the biggest difference in the sound but the right receiver can sure make those speakers shine. Even my wife mentioned that the Marantz seemed to provide a clear sound and she is someone who believe Bass is good, treble and midrange are bad.

My only criticism would be the small status display and the On/Standby status LED. Since the status light is turned off when the system is on, the only way to tell if the receiver is on is by the small display which typically has 2 to 4 letters on it (CD, REC1, etc). It would have been nice if the status light was also lit when the receiver was on. Picky I know, but still annoying.
